IMPROVEMENT iN GATES.

v'.lhe Schedule referred to ln these Letters Patent and making part of the same.

To all whom fit may concern:

Be it known that I, JACKSON NVBIGHT, of Versailles, in the'county of Brown and Statefof Illinois,

have invented a new and useful Improvementiin Gates; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others -skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

My invention relates to farm-gates, and' my object is to introduce tothe publiccertain improvements thereon, which I will first describe in connect-ion with all that is necessary to a full understanding thereof, and then clearly point 'out in my claim.

In the aTccompanyi-ng drawingv Figure l represents a sectional elevation of the gate and operating parts, on the line a: :l: of fig. 2.

Figure 2 is a side elevation', partly in section.

Figure 3 is a detailed view, showing the inside of the fastening-post.

Similar letters of reference parts.

A represents the gate.

B is the fastening-post.

G is the pivot-post of the gate. These posts arel snpliorted by a frame-work, D, from "the platform E, the frame consisting of three back' stationary posts, connected together' by cross-timbers, F, overhead.

indicate corresponding Thecross-tirnber F is connected with the gate-post. -B by the timber G, which extends over the roadway,

anali supports the top end of the pivot-post O, as seen in U. 2.

The gate is held by the weights H H inV nearly a balanced position by means ofthe cords I I, which pass up over pulleys J J, with their ends wound in opposite directions around the pivot-post C, as represented in iig. 1.Y

K vK are levers, which have their fulcruin in back posts L L. lheir inner ends are connected with the sway-beam M, which beam is pivoted to the center back post N, so that it will rock freely on its pivot.

O O are. loose arms, pivoted to the sway-beam lil, the lower ends of which are held iu position by the guide-pieces P l on the cross-bar R.

The arms O serve to unfasten the gate bymeans oi' the adjustable block S, which block is attached to the iiistening-bars 'I l of the gate.

Vhen-the gateis closed,as seen in the drawing,

the arms O are in contact with each side of the upper' end of the block S.

When the fastening-rails of -the gate are raised for opening the gate, the block S is forced down by the arms, these rails being pivoted to the gate at the points U U.

V V are cords, which are attached to the levers K K at the points WW, and, passing up over the stands X X, they are Wound around the pivot gate-post G in opposite directions, as seen in the drawing, so that, by depressing either of' the levers the tendency is to revolve the post and open the gate.

The opening ot the gate is made automatic by the arms O O and the depression ofeither end of the sway-beam M. j

Ihe action of the arms O on the top of the block S is to force the block down, which action raises the opposite ends 'of the fastening-rails T, leaving the gate free to be swung in either direction, as may be relquired. l

The levers K are operated by means of the hanging rods Y Y on each side of the gate, or they-may `be operated on the outside of the posts by taking hold of the vlevers themselves.

By this arrangement the gate maybe opened in .il either direction by aA person on horseback or in acar liage, and that it may be held in any position for the passage of stock, or dividingI docks, or counting sheep.

or other droves of animals.

Having thus described my invention, 4 I clainras new and desire to secure by Letters Patent- 1. The pivoted sway-beam M, arms O O, and .block S, all combined, constructed, and applied to the fastening-bars to unlatch the gate, in the manner described.

2. The unlatching device M-O O S and the ope-n-y ing device VV G, combined, as described, with levers K K and rods Y Y, to nnlatch and open the gate in l `quick succession, and by the same actuating force, as

described.
